(CBS) 2011 was the year of winning, tiger blood and goddesses, but Charlie Sheen says those days are behind him.

The actor made an appearance at Fox's Television Critics Association party on Sunday night, where he discussed last year's meltdown, "Two and a Half Men" and his upcoming FX series, "Anger Management."

"I'm not crazy anymore. That was an episode," Sheen told reporters, according to People magazine. "I think I'm a different person than I was yesterday. Everything is a lot more mellow and focused and much more rooted in reality."

The actor also said he's excited for his new gig, based on the 2003 Adam Sandler/Jack Nicholson film of the same name. Sheen will play an anger management therapist with two groups of patients - one a traditional therapy group, the other a group of incarcerated prisoners.

"It's exciting to be in a situation where the people I work with are excited about my input. That hasn't happened in a long time. But I still know my strengths and weaknesses," he said, according to the Los Angeles Times.

The Hollywood Reporter says that casting is underway and "Anger Management" is set to begin production in March. If the first 10 episodes meet a certain ratings threshold, THR adds, the series will be greenlit for an additional 90 episodes.

Sheen also told reporters that he is now goddess-free and spending more time with his children, People reports. "I've been spending a lot of time with the kids, a lot of time with the family and I'm getting back into work mode," he said. "I'm a single guy hanging out with my children."

As for "Two and a Half Men," Sheen felt killing off his character (who was struck by a subway train) was "a little mean-spirited," but had kind words for the show's new star, Ashton Kutcher.

"[Kutcher] doing a good job. But it's a different show now," he said, according to USA Today. "I thought the moment at the urn with the smoke of my body and his reveal at the window was one of the great television moments of all time."
